If you have a handful of users streaming large movie files over NFS, RAM is not going to be a bottleneck. One of my ultra low-end server (Turion MT-37 2.0 GHz, 512 MB RAM, five 500-GB SATA disk in a raidz1, consumer-grade Nvidia GbE NIC) running an old Nevada b55 install can serve large files at about 650-670 Mb/sec over NFS. CPU is the bottleneck at this level. The same box with a slightly better CPU or a better NIC (with a less CPU-intensive driver that doesn't generate 45k interrupt/sec) would be capable of maxing out the GbE link. -marc _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
